Hello,
I have to subj fo clarification:
In a hub & spoke environment, I have read on many books & other
resources stating to use "frame-relay map ip <x.x.x.x> <DLCI no> to map
the appropriate IP address to its corresponding DLCI on the FR routers.
While I understand that this is a MUST for Spoke routers (since the
Inverse ARP only works on directly connected links)
e.g. On Spoke routers,
interface Serial0
ip address 172.16.2.2 255.255.255.0
encapsulation frame-relay
ip ospf priority 0
no fair-queue
clockrate 64000
frame-relay map ip 172.16.2.3 600 broadcast
frame-relay map ip 172.16.2.4 600 broadcast
frame-relay map ip 172.16.2.1 600 broadcast
no frame-relay inverse-arp
... but on the Hub, wouldn't it make more sense just to stay with
Inverse ARP by "frame-relay inverse-arp" , since the Hub will need to
have physical direct connections to all the Spokes anyway??
e.g. On Hub,
interface Serial0
ip address 172.16.2.1 255.255.255.0
encapsulation frame-relay
frame-relay inverse-arp
Please add something or disprove if i'm wrong.
Thank You,
L.
